Parsimony is an important principle of the scientific method for two reasons.

What is a phylogenetic tree and what is its purpose?

A phylogenetic tree is a diagram that represents evolutionary relationships among organisms. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors.
